Specification of Letters Patent.

Application filed November 11, 1912. Serial No. 730,669. V

To all 'whom z' may concern Be it known that I, FRANK KOPPLIN, a citizenof the United States, residing at Chicago, in the county of Cook andState of Illinois, have invented certain new and useful Improvements inWheel-Hub Flanges, of which the following is a specification.

It has become more or less common to provide wheel hubs with annularmetallic bands adjacent to the central' portion thereof, these bandshaving outwardly extending flanges through which bolts are passed whichclamp the front and back flanges closely against the inner ends of thespokes. These metallic bands with their outwardly extending flanges arecommonly termed as a whole flanges7 'Ihe band portion may becomparatively short and the hub may be provided with a point band, orthe band portion may be extended out to the outer end of the hub inwhich case it is of a somewhat tapered form, and the point band isdispensed with. The present invention relates to such hub protectingmembers and to the combination with the hub, or wooden central portionof a metallic reinforcing and protecting member.

The objects of the present invention are to increase the strength andeffectiveness of such hub flanges or protectin devices; to combine witha hub, a front ange or protecting member having an inwardly extendingring or flange; and to provide such advantages and improvements as willbe more fully described hereinafter.

In the accompanying' drawings illustrating my invention, Figure 1 is aside view of a hub with a front flange embodying the principal featuresof this invention, parts being broken away or shown in sect-ion; andFig. 2 is an end view as seen from the right hand end of Fig. l.

As indicated in these drawings, 3 represents a hub of wood or othersuitable material which isl provided with mortises 4f for receiving thespokes. The hub is provided with a back flange 5 which may be made ofany ordinary or preferred form of construction. It is also provided witha frontliange 6 embodying the principal features of this invention. Theoutwardly extending parts 7 and 8 of these two flanges are provided withholes 9 to receive bolts for bolting them together and against the innerends of the spokes. The tubular or cylindrical portion l0 of the flange6 preferably extends out slightly beyond the end of the hub 3 and isprovided with an inwardly projecting flange or ring 11. This ring orannular member is preferably made integral with the main cylindricalportion 10 of the flange 6, but in some instances may be made separatelyand attached thereto by means of rivets or in any other suitable mannerif desired.- The inner face of the ring 11 is preferably beveled orcurved substantially as indicated at 12 so that the inner edge of thering is thicker than the outer edge thereof. By means of thisarrangement the inner ed e is strengthened and the inner face of t ering may be made to fit closely against the outer end of the hub.

It will be readily seen that by means of my improved construction, theflange or metallic cylinder which fits around the outer periphery of thehub is strengthened at its outer end to a great degree so that it willnot be apt to be jammed or bent when the outer end strikes against anyhard or unyielding object. With such hub flanges or bands as heretoforecommonly used, when the end of the hub struck some hard or unyieldingobject the band would be jammed in and, at times the end of the hubwould be broken or pressed inwardly to such a great extent that it wouldbe impossible to unscrew the axle nut. With my protecting ring orinwardly extending flange, the end of the wood is protected to such anextent that it would be almost impossible to break or injure the end ofthe hub, particularly if the flange is made suiiiciently strong inproportion to the size of the hub.

Having thus described my invention what I claim and desire to secure byLetters Patent is:

l. A hub ange having an integrally formed flange or ring extendinginwardlyr i at one end thereof, said ring having a beveled or recedinginner surface, whereby it is thicker at its inner periphery than at itsouter periphery.

2. The combination With a Wooden hub, of thicker than the outer portionand may come a hub flange having an inwardly extending in contact Withthe Wood before the outer flange or ring at the end thereof, ofsubportion engages with the same.

stantially the same Width as the Wood at FRANK KOPPLIN. 5 the end of thehub, the face of said ring Witnesses:

toward the Wood being tapered or beveled so l vIRENE FORREST,

that the inner portion of the ring will be EDWARD H. TILLsoN.
